MIDI Keyboard triggers a metronome?

Hello all. Apologies for the beginner question but I’ve just hooked up a MIDI keyboard to renoise. I loaded a sample pack in the Reaktor player and I notice whenever i strike a chord on the MIDI keyboard, the instrument plays the chord as expected, but it also triggers the start of a beep-boop-beep-boop metronome that I don’t know how to disable. It doesn’t sound like the Renoise-level metronome but one of its own. I’ve no idea how to stop this and it’s driving me batty…

Thanks in advance.

edit nevermind, i actually had some software running at the OS level that was triggering its own MIDI events. Had nothing to do with Renoise.
